Amar’s acid tongue has scalded many a mover and shaker in the past but rarely has a politician – or anyone for that matter – used such language against a businessman on tape meant for public broadcast.

As for Mukesh’s estranged younger brother Anil, the Samajwadi Party leader told NDTV last night: “I love him, I like him and I trust him fully.”

Amar’s unequivocal declaration of his dislikes and likes was publicised on a day the power people were trying to guess who belonged to which camp by scanning the guest lists for the wedding and Mukesh’s birthday party in Jamnagar.

The Khans who were not invited to the wedding — Shah Rukh and Aamir — were apparently called for Mukesh’s bash. Sound bites from the two are also believed to have figured in a 40-minute biopic that Mukesh’s wife Nita commissioned as a surprise birthday gift for him.

In the television interview, asked why Shah Rukh was not invited to Abhishek’s wedding, Amar said it does not mean that those who have not been invited are enemies.

“As far as Shah Rukh is concerned, even I have got very friendly and positive feelings for him. I have never taken a dig against Shah Rukh,” he said.

Amar referred to Sonia Gandhi as “queen bee” and but did not rule out a tie-up with the Congress.

“Not in the near future. But with friends like Pranab Mukherjee, (Priya Ranjan) Das Munshi and with people like Prakash Karat, they are the real moderators,” he said, asked whether the two parties could make up and join hands.

Sources associated with the corporate world said Amar’s tirade against Mukesh could have been set off by the rebuff that greeted the politician’s alleged attempts to worm his way into the family.

Mukesh and Nita were uneasy about the manner in which Amar befriended Anil, the sources said. He is also believed to have used Amitabh Bachchan — the star and Anil are friends — as a conduit to get through to the younger Ambani.

The source claimed that Mukesh and Nita had warned Anil and his wife Tina several times to avoid being associated with a particular party or politician as it would be detrimental to their business interests. “But by then, Amar had gained in clout and nothing could be done,” the source added.

Mukesh was also believed to have been against Anil entering the Rajya Sabha on a Samajwadi Party nomination.

He “disapproved” of the “delusions of political grandeur” that Amar allegedly fed Anil, more so because a Congress-led regime was in power and there were “signals” it would not be as friendly to the Samajwadi Party as the BJP.

Mukesh was always careful to be politically neutral, the source said. He believes that his father’s rise was as much by dint of hard work as by his “conviction” that while industrialists needed to cultivate politicians, they also had to know where to draw the line, the source said.
